Abstract
A process for forming cement clinker using mill scale that may have hydrocarbons associated therewith. Normal feedstock material is preheated and then transferred to a combustion area. The mill scale is also transferred to the combustion area where, during the process of burning a material, the unwanted hydrocarbons are volatilized and converted to harmless gaseous products (by combustion) that can be passed to the atmosphere. The combustion area may be a precalciner or may be the feed end of the rotary kiln if the rotary kiln has an adequate temperature profile. The remaining mill scale and feedstock material are thoroughly mixed and blended and the mill scale is diffused and combined with the feedstock material as the mill scale and the feedstock material move from the feed end toward the heat-source end of the rotary kiln to form cement clinker.
